Study Notes
Mitosis Phases
- During prometaphase, the nuclear envelope breaks down, and the chromosomes condense and become visible as separate structures.
- The classic chromosome structure appears during prophase.
Cell Cycle and Mitosis
- The main outcome of mitosis is the production of two daughter cells that are genetically identical to the parent cell.
- The replication of a cell's DNA occurs during the S (synthesis) phase of the cell cycle.
- Many eukaryotic cells duplicate approximately every 24 hours, meaning the frequency of cell duplication is roughly once a day.
